Receptance-Based Computation of Stability Crossing Curves for Single-Input-Multiple-Output Second-Order Linear Systems with Two Time-Delays

, 2022
For a complete stability analysis of multi-dimensional controlled systems modeled in the framework of second-order linear differential equations with two time-delays, the determination of stability crossing curves (or stability switching curves) within ...

A receptance-based method for frequency assignment via coupling of subsystems

, 2019
This paper presents a theoretical study of the frequency assignment problem of a coupled system via structural modification of one of its subsystems. It deals with the issue in which the available modifications are not simple; for example, they are not ...

Oszacowanie Odpowiedzi Struktury Mechanicznej na Dowolne Wymuszenie

Engineering Transactions, 1973
A method is proposed for estimation of the response of a mechanical system to an arbitrary excitation. Starting with a general model of the structure and three kinds of damping, the concept of maximum receptance playing the role of dynamic ...
